Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
The first embodiment of the invention relates to an access method of a terminal. The method and the device are used for enabling the personalized frequency band requirement of the terminal to be known by the base station, and then enabling the base station to allocate a proper working frequency band for the terminal to be accessed into a wireless network.
The following describes details of the implementation of the access method of the terminal in this embodiment in detail, and the following is only for facilitating understanding of the details of the implementation of this solution and is not necessary for implementing this solution.
Fig. 1 is a flowchart of an access method of a terminal in this embodiment, and the method is applicable to the terminal. The terminal may be a smart phone, or may be a smart terminal capable of installing a Subscriber Identity Module (SIM), such as a tablet computer (PAD). The method may include the following steps.
In step 101, a frequency band requirement table of the terminal is determined according to the remaining power of the terminal.
The frequency band requirement table comprises the frequency bands which the terminal desires to connect.
It should be noted that the frequency band to which the terminal is expected to connect may be one frequency band or multiple frequency bands, for example, multiple frequency bands with priorities from high to low may be sequentially obtained according to the remaining power of the terminal and the expected value of the terminal, so that the frequency band of the base station can be matched with at least one of the multiple frequency bands, and the frequency band is used as an operating frequency band and allocated to the terminal.
In a specific implementation, every preset time interval, the terminal performs the following operations: determining the strength of the received signal according to the corresponding relation between the residual electric quantity and the strength of the received signal of the terminal; determining the frequency band which is expected to be connected by the terminal according to the corresponding relation among the received signal strength, the received signal strength and the frequency band which is expected to be connected by the terminal; and determining a frequency band demand table according to the frequency band to which the terminal expects to be connected.
Note that the frequency band refers to a frequency range of electromagnetic waves, and has a unit of Hz. For example, when the remaining power of the terminal is 30%, the received signal strength of the terminal is a fourth strength, and the frequency bands to which the corresponding terminals expect to connect are D0Hz to D1 Hz; when the residual capacity of the terminal is 60%, the received signal strength of the terminal is a third strength, and the frequency band to which the corresponding terminal is expected to be connected is C0 Hz-C1 Hz; when the residual capacity of the terminal is 90%, the received signal strength of the terminal is a second strength, and the frequency band to which the corresponding terminal is expected to be connected is B0 Hz-B1 Hz; when the residual capacity of the terminal is 100%, the received signal strength of the terminal is a first strength, and the frequency band to which the corresponding terminal is expected to be connected is A0 Hz-A1 Hz; according to the corresponding relation, the received signal strength of the terminal and the frequency band expected to be connected by the terminal can be determined, and then the frequency bands expected to be connected by the terminal are combined to generate a frequency band demand table. The preset time duration may be set according to an actual use condition, for example, the preset time duration is set to be 1 minute, 2 minutes or other time intervals, which is not limited to the above example, and other time intervals that are not illustrated are also within the protection scope of the present invention, and are not described herein again.
Wherein, the corresponding relation between the residual capacity and the received signal strength of the terminal comprises: if the higher the received signal strength is determined to be, the more power is saved by the terminal, and the more the remaining power is.
For example, when the received signal strength is the second strength, it is known that the remaining power of the current terminal is 90%, if the received signal strength is reduced during the moving process of the terminal (which may be caused by a bad network signal where the terminal is located or when the terminal is located between two communication cells), for example, the received signal strength is reduced to the third strength, the terminal needs to use more power during the process to support the lower signal strength, that is, the third strength; the remaining capacity of the terminal may be reduced to 60%.
The corresponding relationship between the received signal strength and the frequency band to which the terminal is expected to be connected includes: if it is determined that the received signal strength is higher, the frequency band to which the terminal desires to connect is lower.
It should be noted that, if the terminal desires to obtain a higher received signal strength, the frequency band of the desired connection needs to be reduced. For example, when a terminal downloads a certain video file, the received signal strength needs to be high to ensure smooth downloading, and the frequency band desired to be connected by the terminal is a lower frequency band, for example, if there are two frequency bands, one frequency band is A0 Hz-A1 Hz, the other frequency band is B0 Hz-B1 Hz, where A0 is smaller than B0 and A1 is smaller than B1, it may be determined that the desired frequency band of the terminal is A0 Hz-A1 Hz.
In step 102, a first broadcast message is sent to the blockchain network.
The first broadcast message comprises a frequency band requirement table and an identifier of the terminal.
It should be noted that the Blockchain (Blockchain) is a decentralized distributed database. The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The main function of the blockchain is to store information, and any information that needs to be stored can be written into the blockchain network and also can be read from the blockchain network. Anyone can set up a server to join the blockchain network to become a node of the blockchain network. The blockchain network has no central node, each node is equal, each node can write or read data, and all nodes can keep synchronization so as to ensure the consistency of the blockchain network. In a narrow sense, the blockchain is a distributed account book which is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence and is guaranteed in a cryptographic mode and cannot be tampered and forged. Broadly speaking, the blockchain technique is a completely new distributed infrastructure and computing paradigm that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secure data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data.
In step 103, in response to the frequency band allocation message sent by the base station, the wireless network provided by the base station is accessed using the operating frequency band carried in the frequency band allocation message.
The working frequency band is the frequency band determined by the base station according to the frequency band requirement table.
In a specific implementation, a base station is searched according to a frequency band requirement table to obtain an identifier of a preset base station, wherein the preset base station is a base station which responds to the frequency band requirement table sent by a terminal and sends a frequency band allocation message to the terminal, and the distance between the base station and the terminal is smaller than or equal to a preset distance; responding to a frequency band allocation message sent by a preset base station, and acquiring a working frequency band, wherein the frequency band allocation message comprises the working frequency band; and accessing the working frequency band into a wireless network provided by a preset base station.
It should be noted that the baseband processor module in the terminal may support communication in any one of the communication network modes of the second generation communication network, the third generation communication network, the fourth generation communication network or the fifth generation communication network. The distance between the searched base station and the terminal is smaller than or equal to a preset distance, for example, the preset distance is 500 meters, and the terminal searches for the base station within the range of the distance smaller than or equal to 500 meters, so as to obtain the identifier of the preset base station.
In the embodiment, the frequency band requirement table of the terminal is determined according to the residual electric quantity of the terminal, and the frequency band requirement table is sent to the block chain network, so that each base station in the block chain network can know the requirement of the terminal on the frequency band, and the terminal is safer and more credible when selecting the frequency band through a trust mechanism of the block chain and the characteristic that a block chain account book cannot be tampered, can be traced, guarantees the safety and benefits of both parties of a transaction, and improves the voice call and network speed experience of the terminal; and then when the frequency band of the base station can be matched with the frequency band demand table, the base station distributes a proper working frequency band for the terminal through the frequency band distribution message, and the terminal can be accessed into a wireless network through the working frequency band, so that the individual requirements of the terminal are met, the frequency band resource of the base station is saved, and the customer experience degree is improved.
A second embodiment of the present invention relates to an access method of a terminal. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: before determining the frequency band requirement table of the terminal according to the remaining power of the terminal, a second broadcast message needs to be sent to the blockchain network, so that the terminal can pass the authentication of the client information server.
Fig. 2 is a flowchart of an access method of a terminal in this embodiment, and the method can be applied to the terminal. The terminal may be a smart phone, or may be a smart terminal capable of installing a Subscriber Identity Module (SIM), such as a tablet computer (PAD). The method may include the following steps.
In step 201, according to the international mobile subscriber identity of the terminal, the operator corresponding to the terminal is determined, and the customer service password of the operator is obtained.
It should be noted that the International Mobile Subscriber Identity (IMSI) may also be replaced by other identifiers, for example, a Temporary Mobile Subscriber Identity (TMSI) in a fifth-generation communication network, as long as a corresponding operator can be found according to the identifier. In different communication networks, the identifier may be set according to actual situations, and is not limited to the above example, and other non-example information is also within the protection scope of the present invention, and is not described herein again.
In step 202, a second broadcast message is generated according to the identity authentication information of the terminal and the international mobile subscriber identity of the terminal.
It should be noted that the identity authentication information may be identity information of a user using the terminal (for example, an identity card number of the user, etc.), or may be a physical address of the terminal, as long as the identity authentication information can identify the terminal, the identity authentication information may be set according to an actual situation, and is not limited to the above example, and other non-example identity authentication information is also within the protection scope of the present invention, and is not described herein again.
In step 203, an encryption result is generated based on the service password of the operator and the timestamp of the second broadcast message.
The second broadcast message comprises the identity authentication information of the terminal, the international mobile subscriber identity of the terminal, the time stamp of the second broadcast message and the encryption result.
It should be noted that the encryption result is to ensure the security of the second broadcast message, and when a certain network element receives the second broadcast message, if the encryption result cannot be decrypted correspondingly, the network element cannot acquire the content in the second broadcast message; if the network element can successfully decrypt the encrypted result, the network element can acquire the content in the second broadcast message, that is, the identity authentication information of the terminal carried in the second broadcast message, the international mobile subscriber identity of the terminal and other information.
In step 204, a second broadcast message is sent to the blockchain network.
If the encryption result in step 203 is the first encryption result, after the client information server receives the second broadcast message, the second encryption result is generated according to the operator service password corresponding to the international mobile subscriber identity (for example, the mobile phone number is 18611112222) of the terminal stored in the client information server and the timestamp of the second broadcast message; and comparing the first encryption result with the second encryption result, if the first encryption result is consistent with the second encryption result, the client information server can acquire the identity authentication information of the terminal in the second broadcast message, so that the client information server verifies the terminal, and the terminal is determined to be a legal terminal which is the terminal passing the identity authentication of the client information server.
In step 205, a frequency band requirement table of the terminal is determined according to the remaining power of the terminal.
In step 206, a first broadcast message is sent to the blockchain network.
In step 207, in response to the frequency band allocation message sent by the base station, the operating frequency band carried in the frequency band allocation message is used to access to the wireless network provided by the base station.
It should be noted that steps 205 to 207 in this embodiment are the same as steps 101 to 103 in the first embodiment, and are not described herein again.
In the embodiment, the second broadcast message comprising the identity authentication information of the terminal, the international mobile subscriber identity of the terminal, the timestamp of the second broadcast message and the encryption result is sent to the blockchain network, so that the client information server can verify the identity of the terminal after receiving the second broadcast message, the terminal becomes a legal terminal, and the communication safety is ensured; furthermore, the frequency band requirement table of the terminal is determined through the residual electric quantity of the terminal, and the frequency band requirement table is sent to the block chain network, so that each base station in the block chain network can know the requirement of the terminal on the frequency band, and the terminal is safer and more credible when the frequency band is selected through a trust mechanism of the block chain and the characteristic that the block chain account book cannot be tampered, and can trace back, the safety and benefits of both sides of a transaction are guaranteed, and the voice communication and the network speed experience of the terminal are improved.
A third embodiment of the present invention relates to an access method for a terminal. Fig. 3 is a flowchart of an access method of a terminal in this embodiment, and the method can be applied to a base station. The method may include the following steps.
In step 301, in response to a first broadcast message sent by a terminal, a frequency band requirement table of the terminal is obtained.
The first broadcast message comprises a frequency band requirement table and an identifier of the terminal.
It should be noted that the frequency band requirement table is obtained by the terminal according to the remaining power, specifically, the received signal strength of the terminal is inversely proportional to the power used by the terminal, that is, the higher the received signal strength is, the more the terminal saves power, and the more the corresponding remaining power is. Meanwhile, the received signal strength of the terminal is inversely proportional to the frequency band to which the terminal desires to connect, i.e., the higher the received signal strength, the lower the frequency band to which the terminal desires to connect. And determining a frequency band demand table suitable for the terminal according to the corresponding relation and the self residual electric quantity of the terminal at the current moment.
Every time a preset time length passes, the terminal calculates and sends a frequency band requirement table to the block chain network, so that the base station can obtain the latest frequency band requirement of the terminal. The preset time duration may be set according to an actual use condition, for example, the preset time duration is set to be 1 minute, 2 minutes or other time intervals, which is not limited to the above example, and other non-example information is also within the protection scope of the present invention, and is not described herein again.
In step 302, the operating band allocated to the terminal is determined according to the band requirement table.
In a specific implementation, if it is determined that a frequency band in the frequency band requirement table is in an idle state, the frequency band is used as a working frequency band; and if the frequency band in the frequency band demand table is determined to be in a non-idle state, calculating to obtain the working frequency band according to the frequency band in the frequency band demand table.
It should be noted that, if it is determined that the frequency band in the frequency band requirement table is in the non-idle state, it indicates that the frequency band cannot be allocated to the terminal, a frequency band closest to the frequency band in the frequency band requirement table of the terminal needs to be searched, and the frequency band obtained by the search is in the idle state, and the frequency band obtained by the search can be set as the working frequency band.
In step 303, a band assignment message is sent to the terminal.
It should be noted that the frequency band allocation message includes an operating frequency band, and after receiving the operating frequency band, the terminal may use the operating frequency band to access to a wireless network provided by the base station.
In the embodiment, the specific requirements of the terminal on the frequency band are acquired through the received frequency band requirement table, and then the adaptive working frequency band is allocated to the terminal, so that the terminal can access the wireless network provided by the base station by using the working frequency band, the frequency band resource of the base station is saved, the personalized requirements of the terminal are met, and the customer experience degree is improved.
A fourth embodiment of the present invention relates to an access method for a terminal. The fourth embodiment is substantially the same as the third embodiment, and mainly differs therefrom in that: and according to the frequency band in the frequency band demand table, obtaining the working frequency band of the terminal by searching the block chain account book.

In step 401, in response to a first broadcast message sent by a terminal, a frequency band requirement table of the terminal is obtained.
It should be noted that, the content of step 401 in this embodiment is the same as that of step 301 in the third embodiment, and is not described herein again.
In step 402, according to the frequency band in the frequency band requirement table, a block chain book is searched, and the working frequency band of the terminal is determined.
It should be noted that the blockchain ledger is a distributed ledger, and the ledger can share, copy and synchronize data among network members, and in the ledger, transaction information among various network nodes is recorded. Because each terminal and each base station can be used as a node of the block chain, the dynamic query of the real-time frequency band information of each base station through the block chain becomes possible, the frequency band which is most matched with the frequency band demand list of the terminal is ensured to be searched for the terminal, and the searched frequency band is ensured to be in an idle state.
The block chain account book comprises a frequency band demand table determined by the terminal according to the residual electric quantity at the current moment.
It should be noted that the frequency band requirement table in the block chain book is updated once every preset time period, so as to ensure that the frequency band requirement table can reflect the latest requirement of the terminal at the current time. The preset time duration may be set according to an actual use condition, for example, the preset time duration is set to be 1 minute, 2 minutes or other time intervals, which is not limited to the above example, and other non-example information is also within the protection scope of the present invention, and is not described herein again.
In step 403, a frequency band allocation message is sent to the terminal.
It should be noted that step 403 in this embodiment is the same as step 303 in the third embodiment, and is not described herein again.
In this embodiment, by searching the block chain account book, the working frequency band matched with the frequency band requirement table of the terminal is obtained, so that the working frequency band allocated to the terminal can fully meet the personalized frequency band requirement of the terminal at the current moment, and meanwhile, the frequency band resource of the base station is saved, and the customer experience is improved.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
A fifth embodiment of the present invention relates to an access system for a terminal, and as shown in fig. 5, the system specifically includes: a terminal 501, a base station 502, and a client information server 503; the terminal 501 is configured to perform the access method of the terminal described in the first or second embodiment; the base station 502 is configured to perform the access method of the terminal described in the third or fourth embodiment; the client information server 503 is used for authenticating the terminal 501.
In one specific implementation, the base station 502 and the terminal 501 and the client information server 503 are both nodes of a spectrum federation blockchain, and the base station 502 and the terminal 501 belong to the same operator. Each base station is used as a service node of a block chain to be accessed into the block chain, and provides access service for other intelligent terminals. Note that, the created block of the federation chain stores information such as the blockchain id and the public key of the base station 502 and the blockchain id and the public key of the client information server 503, and the above devices together serve as the creation node of the federation chain to manage the federation chain. Other base stations with the same function as the base station 502 may also be included in the blockchain network to facilitate the access of the terminal 501.
The terminal 501 is registered in the operator business hall, so that the client information server 503 can obtain the first usage information of the user using the terminal 501, where the first usage information may specifically include account opening information and a service password of the operator, and the account opening information may be identity information of the user. For example, the terminal 501 is a smart phone, the IMSI of the mobile phone card installed on the smart phone is 18611112222, and the corresponding operator is connected, so that the connected client information server 503 stores identity information such as an identity number of a user using the smart phone, and also allocates a corresponding connected client service password to the smart phone, so as to facilitate the client to inquire call charge information.
After the terminal 501 is powered on, the terminal 501 generates a second broadcast message according to the identity authentication information of the terminal and the IMSI of the mobile phone card installed on the terminal; and sends the second broadcast message to the blockchain network after signing with the private key of the terminal 501. The second broadcast message includes the IMSI (e.g., the mobile phone number 18611112222) of the mobile phone card installed on the terminal 501, a timestamp of the second broadcast message, and a first encryption result, where the first encryption result is generated according to the operator service password corresponding to the terminal 501 and the timestamp of the second broadcast message.
After receiving the second broadcast message, the client information server 503 first verifies the private key signature of the second broadcast message; if the private key signature passes the verification, generating a second encryption result according to an operator customer service password corresponding to the mobile phone number 18611112222 of the terminal 501 stored in the private key signature and a timestamp of the second broadcast message; comparing the first encryption result with the second encryption result; if the first encryption result is consistent with the second encryption result, the client information server 503 generates a third broadcast message according to the blockchain identifier of the terminal 501, the mobile phone number 18611112222 and the public key, signs the third broadcast message by using the private key of the client information server 503, and sends the third broadcast message to the blockchain network.
It should be noted that the first encryption result and the second encryption result are calculated according to a predetermined algorithm, which may be an encryption algorithm commonly used in the blockchain network, or may be other encryption algorithms, and the encryption algorithm may be set according to practice, and is not limited to the above example, and other information that is not illustrated is also within the protection scope of the present invention, and is not described herein again.
The terminal 501 determines a frequency band requirement table suitable for the terminal 501 according to the remaining power of the terminal 501 at the current time, where the frequency band requirement table includes a frequency band to which the terminal 501 is expected to connect. Every time interval preset duration, a private key of the terminal 501 is used to sign a first broadcast message including the frequency band requirement table and the identifier of the terminal 501, and the first broadcast message is sent to the block chain network, so that all base stations in the block chain network can receive the frequency band requirement table of the terminal 501, that is, the requirement of the terminal 501 for the frequency band can be known by the base stations. The first broadcast message further includes the cell phone number 18611112222 of the terminal 501, the blockchain identifier of the terminal 501, and the third broadcast message.
It should be noted that the received signal strength of the terminal 501 is inversely proportional to the power used by the terminal 501, that is, the higher the received signal strength is, the more the terminal 501 saves power, and the more the corresponding remaining power is. Meanwhile, the received signal strength of the terminal 501 is inversely proportional to the frequency band to which the terminal 501 desires to connect, i.e., the higher the received signal strength, the lower the frequency band to which the terminal 501 desires to connect. According to the correspondence and the remaining power of the terminal 501 at the current time, the frequency band requirement table applicable to the terminal 501 can be determined. The preset time duration may be set according to an actual use condition, for example, the preset time duration is set to be 1 minute, 2 minutes or other time intervals, which is not limited to the above example, and other non-example information is also within the protection scope of the present invention, and is not described herein again.
The terminal 501 searches for base stations through the baseband processor module to know the identities of a plurality of base stations, for example, the identity of base station 502 and the identity of base station 504. It should be noted that the baseband processor module in the terminal 501 may support communication in any one of the communication network modes of the second generation communication network, the third generation communication network, the fourth generation communication network, or the fifth generation communication network. The distance between the searched base station and the terminal 501 is less than or equal to a preset distance, for example, the preset distance is 500 meters, and then the terminal 501 searches for a base station within a range of which the distance is less than or equal to 500 meters.
Terminal 501 may send access requests to both base station 502 and base station 504, but because only base station 502 has a frequency band that matches the frequency band to which terminal 501 currently desires to connect,
the base station 502 allocates an operating frequency band to the terminal 501 so that the terminal 501 can access the wireless network provided by the base station 502.
It should be noted that, before acquiring the access request sent by the terminal 501, the base station 502 receives a first broadcast message in the block chain network, and further verifies a private key signature of the first broadcast message, if the verification is passed, it is determined whether a frequency band in the frequency band requirement table is in an idle state, and if the verification is in the idle state, the frequency band is allocated to the terminal 501 as a working frequency band; otherwise, according to the frequency band in the frequency band requirement table, the working frequency band is calculated and obtained (for example, the currently idle frequency band of the base station 502 is searched, and the frequency band closest to the frequency band in the frequency band requirement table is obtained as the working frequency band), so that the terminal 501 can access to the wireless network provided by the base station 502.
Or, the base station 502 searches the block chain account book according to the frequency band in the frequency band requirement table, finds the latest idle frequency band in the account book, and the idle frequency band matches with the frequency band expected to be connected at the current time broadcasted by the terminal 501, so that the terminal 501 can access to the wireless network provided by the base station corresponding to the frequency band.
In the embodiment, a frequency band requirement table of the terminal is determined according to the residual electric quantity of the terminal, and the frequency band requirement table is sent to a block chain network, so that each base station in the block chain network can acquire the requirement of the terminal on a frequency band; and then when the frequency band of the base station can be matched with the frequency band demand table, the base station distributes a proper working frequency band for the terminal through the frequency band distribution message, and the terminal can be accessed into a wireless network through the working frequency band, so that the individual requirements of the terminal are met, the frequency band resource of the base station is saved, and the customer experience degree is improved.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
